Here is the abstract: A classical point electron radiates when it accelerates. However, there are classical electron models with extended charge distributions which can accelerate and/or deform without radiating. Can a model be contrived that will undergo radiationless motion while accelerating (on the average) over a distance large compared to its size? The answer is no: we prove that the “center” of the electron is always closer than the electron “diameter” to a fictitious point undergoing constant-velocity motion, if the electron's motion is radiationless. Yeah, I miss read it. However, might the hbar arise because you overlooked the motion of the proton in conserving angular momentum? The electron is not orbiting a fixed point. Harry
